Equilibrium temperature anisotropy and black-hole analogues
Daniel K. L. Oi, Jonathan Oppenheim
When long-range interactions are present the usual definition of temperature implies that two systems in thermal equilibrium can be at different temperatures. This local temperatur…
The spectrum of quantum black holes and quasinormal modes
Jonathan Oppenheim
The spectrum of multiple level transitions of the quantum black hole is considered, and the line widths calculated. Initial evidence is found for these higher order transitions in…
Thermodynamics with long-range interactions: from Ising models to black-holes
Jonathan Oppenheim
New methods are presented which enables one to analyze the thermodynamics of systems with long-range interactions. Generically, such systems have entropies which are non-extensive,…
A Thermodynamic Sector of Quantum Gravity
J. Oppenheim
The connection between gravity and thermodynamics is explored. Examining a perfect fluid in gravitational equilibrium we find that the entropy is extremal only if Einstein's equati…
